Digital Archive from an Archaeological Evaluation at St. Mary's Garrison, St Mary's Island, Isles of Scilly, May 2006

This collection comprises reports, site images and records, CAD vector drawings, and spreadsheet data from an archaeological evaluation at St. Mary's Garrison, St. Mary's Island, Isles of Scilly. The works were undertaken by English Heritage between the 9th and 23rd May, 2006 as part of the conservation plan for the monument at risk of coastal erosion. Four trenches were excavated, three across the defensive bank and ditch, the other across a gun platform position. The excavations revealed that the breastwork and gun platform were of a single phase of construction, with some secondary modification to the gun platform outer wall. The defensive earthworks appear to be of Civil War origin, with little refashioning or rebuilding since built, and they thus represent a nationally important survival of 17th-century defensive earthworks.
